Stainless steel fasteners are used extensively throughout industry for both original equipment manufacture as well as for replacement. The stainless steel fastener materials are identified as the B8 class of alloys and are identified in the ASTM Specification A193/193M (Standard Specification for Alloy Steel and Stainless Steel Bolting Materials for High Temperature Service). The corresponding nut specification is ASTM Specification A194/194M.

Our Stainless Steel Fastener plant is equipped with various testing facilities like Tensile Testing Machine also known as tension testing. We also conduct other tests like Hardness Test, IGC Test, Positive Material Identification Test to ensure that all the product going out of our manufacturing plant are the best in terms of quality.

Marking & Shipping Of 304H Stainless Steel Nuts

• Packaging
In generally, If you have no special requirement, we will use the mass packing (bag carbon tray). If you want to do the special packing, please advise us the specific details, pictures or design.

Wooden Box, SUITABLE BAGES OR BOXES

Delivery Detail: 7-15 Days

• Shipping
In generally, our customer often request to delivery by express, plane or sea. Any other better way will be also accepted well.

• Location
Our facility is located a few miles from the Port of Nhava Sheva (Mumbai), the India’s Commercially Important port for foreign waterborne tonnage, and one hour from the Sahara international Airport. Our close proximity to these vital ports along with the speed in which we can process and pack international orders allows us to deliver anywhere in the world within few days.
For domestic shipments, close proximity to interstate highways and rails allow us to provide competitive inland transportation to all over India destinations and ports.

Most Widely Used Austenitic Stainless Steel Modified with a Controlled Carbon Chemistry for Increased Strength to 1500°F (816°C)

Alloy 304/304H has good resistance to atmospheric corrosion, foods and beverages and to many organic and inorganic chemicals in moderately oxidizing to moderately reducing environments. The high chromium content of the alloy provides resistance to oxidizing solutions such as nitric acid up to 55% weight and up to 176°F (80°C).

Alloy 304/304H also resists moderately aggressive organic acids such as acetic. The nickel present in the alloy provides resistance to moderately reducing solutions such as pure phosphoric acid, whatever the concentration, in cold solutions and up to 10% diluted hot solutions. The alloy can also operate successfully in caustic solutions free of chlorides or fluorides at moderate temperatures.

Alloy 304/304H does not perform well in more highly reducing environments such as those containing chlorides and sulfuric acid.

Alloy 304/304H performs well in fresh water service with low levels of chlorides (less than 100ppm). At higher chloride levels the grade is susceptible to crevice corrosion and pitting. For successful performance under these more severe conditions, higher molybdenum content is need such as 316/316L. Alloy 304/304H is not recommended for service in marine environments.

Fabrication Data

Alloy 304/304H can be easily welded and processed by standard shop fabrication practices.

Welding

Alloy 304/304H can be readily welded by most standard processes. After welding Alloy 304/304H it may be necessary to anneal the plate to restore the corrosion resistance lost by sensitization to intergranular corrosion when chromium carbides precipitate in the grain boundaries in the weld heat-affected zone.

Machining

Alloy 304/304H is subject to work hardening during deformation and is subject to chip breaking. The best machining results are achieved with slower speeds, heavier feeds, excellent lubrication, sharp tooling and powerful rigid equipment.

Hot Forming

Working temperatures of 1652–2102°F (750–1150°C) are recommended for most hot working processes. For maximum corrosion resistance, the material should be annealed at 1900°F (1038°C) minimum and water quenched or rapidly cooled by other means after hot working.
